 ## Config System
 - Viper instance is stored in context using a custom key type (`confKeyType`)
-- Use `config.New(path, overrides)` to create a new viper instance
+- Use `config.New(ctx, path)` to create a new viper instance
 - Use `config.RetrieveFromContext(ctx)` to get both viper and the unmarshaled Config struct
 - Formatters can use `v.Sub("formatters." + kind)` to get their own sub-config and unmarshal into their specific config struct
 - Test files must create viper instances and add them to context using `config.AddToContext`
